ETTINGS FOR
STA
Use the Spanning Tree > STA (Configure Interface - Configure) page to
configure RSTP and MSTP attributes for specific interfaces, including port
priority, path cost, link type, and edge port. You may use a different
priority or path cost for ports of the same media type to indicate the
preferred path, link type to indicate a point-to-point connection or shared-
media connection, and edge port to indicate if the attached device can
support fast forwarding. (References to “ports” in this section means
“interfaces,” which includes both ports and trunks.)

“Spanning Tree Commands” on page 1021
P
ARAMETERS
These parameters are displayed:
•
Interface – Displays a list of ports or trunks.
•
Spanning Tree – Enables/disables STA on this interface.
(Default: Enabled)
•
BPDU Flooding - Enables/disables the flooding of BPDUs to other
ports when global spanning tree is disabled ( page 193 ) or when
spanning tree is disabled on a specific port. When flooding is enabled,
BPDUs are flooded to all other ports on the switch or to all other ports
within the receiving port’s native VLAN as specified by the Spanning
Tree BPDU Flooding attribute ( page 193 ). (Default: Enabled)
• Priority – Defines the priority used for this port in the Spanning Tree
Protocol. If the path cost for all ports on a switch are the same, the port
with the highest priority (i.e., lowest value) will be configured as an
active link in the Spanning Tree. This makes a port with higher priority
less likely to be blocked if the Spanning Tree Protocol is detecting
network loops. Where more than one port is assigned the highest
priority, the port with lowest numeric identifier will be enabled.
• Default: 128
